A 5V@4A step down regulator is built in, so that the LattePanda is adequately powered. The underside of the board has a set of female headers that mate with the LattePanda’s CN2 power headers. A set of male headers on the underside of the board also mate with the LattePanda’s female UART headers to access the Cherrytrail chip.

Basic circuit tests and functional tests have been completed and a GUI for the firmware and test program (LABVIEW) has been created for the operation of the STM32F373 MCU.

The protocol for communication is a control protocol created by Mavlink to support various development languages.

There is a USB type A female connector to connect the LattePanda’s audio jack to the audio amplifier built in to the shield and the USB-VCP.
